NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 749,385, dated January 12, 1904.

Application iled February 28, 1903. Serial No. 145,551. (No model.)

To 'r1/ZZ whom t may concern:

Be it known that I, HENRY KAHLMUS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Non-Refillable Bottles, of which the following is a specification.

My invention consists in an improved stopper for bottles, having for its object the provision of a device which while permitting the flow of liquid out of the bottle shall effectually prevent refilling thereof.

A further object of the device is to provide my improved construction with an auxiliary passage for the admission of air to the interior of the bottle, so as to permit of an increased outward` flow of liquid from the main passage through the stopper, at the same time so constructing the auxiliary passage that it `shall be impossible to introduce liquid into the bottle through the same. These objects I attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of one section or part of a bottle-stopper constructed accord- Fig. 2 is a side elevation of the other section of the stopper shown in Fig. l.' Fig. 3 is a sectional plan view of my improved stopper, taken on the line 3 3, Fig. 2; and Fig. 4 is a sectional plan view taken on the line 4 A, Fig. 2.

In the above drawings, A indicates the neck of a bottle within which my improved stopper is held by any of the well-known methods known to the art-as, for example, by some form of cement or interlocking construction between the stopper and said neck.

My improved stopper is constructed, prefb2, above which are a series of longitudinal `i'lutmgs or projections b3, having at about their middle points inwardly-extending raised portions 54.

In the case illustrated the passage has its inner'portion substantially parallel with the passage said portion being, however, extended and opening on the upper end of the stopper at an angle to the longitudinal axis thereof. The passage b opens on the lower face of the stopper and is independent of the passage Z1'.

There are in the portion C of the stopper passages c and c, semicircular in section and forming complete and independent passages with the similarly-placed passages b and b' of the section B, it being, however, noted that a tion C of the stopper and correspondingly countersink the face of the section B for the reception of the same.

, There is a valve c1 iitting the two-part valve-seat b2 c2, there being similarly to the construction of the passage 6 lutings 0*, so

formed as to cooperate with the similarlyformed parts on the iiutings b3 for the prevention of undue motion of the said valve.

A third passage, lying in a plane at` right angles tothe plane of the two passages b c and Z2' o', extends within the portions D and C of the stopper in such a manner as to connect the inner ends of said two passages. sage is formed partly in each of the above portions of thestopper and so unites the ends of the other passages that its plane lies at an angle to the planes of the upper and lower ends of the stopper. There is a valve-seat (Z formed in this third passage and a valve d therefor, there being iiutings on the interior surface of said passage, so as to permit the passage of liquid past the valve as long as it is unseated, and also inwardly-extending points Z2 from Vsaid passage continues at an angle to its former course, finally opening into a groove s in the outer cylindrical surface of the stopper, ending atthe edge of the upper face of the stopper. y

In Fig. 2 is shown the valve 69 for coperation with the valve-seat whose two parts are indicated at Z2 and c6, it being understood that when the two portions of the stopper are put together the portions of the passages described as semicircular in section fit togetherto make a passage circular in section and confine within them said valve b.

When it is desired to pour liquid out of the bottle, it will be seen that the valve 010 will remain away from its seat as long as the bottle is inclined, and liquid tends to flow out while the valve CZ, which rests upon its seat, is forced away therefrom by the pressure of said liquid to an extent sufficient to permit of a continuous flow. Such outiow is materially increased by the use of the passage b5 o5, through which air is free to enter when the bottle is inclined sufficiently, it being noted that when the stopper is in position in the neck of the bottle such neck forms one wall `of this auxiliary passage.

If desired, a tube extending to the bottom of the bottle (shown'in dotted lines at 51) may be inserted in the air-passage, so as to admit air directly to the air-space within said bottle without requiring it to bubble through the liquid contained therein.

Should the attempt be made to force liquid into the bottle through either or both of the passages, it will be found that there is no position in which this can be accomplished without either one of the valves d or 01 being seated' or else being in such unstable position as to be forced to their seats immediately upon the passage of any fluid. It will further be seen that the specific arrangement of passages is such that it is impossible to positively hold the valves from being thus driven or forced to their seats by the iniiow of fluid, which inflow is further hindered by the fact that the valve b9 in the air-passage will interfere with the flow of air out of the bottle in almost any position of the latter except when it is upright, and this is immaterial, since in that position the valve om i s seated. rIhe bend shown in the passage c5 makes it practically impossible to introduce a wire or similar means for preventing the valve b9 from seating.

I claim as my invention l. A stopper for anon-reillable bottle consisting of two sections together forming a substantially cylindrical piece, a passage through said stopper having two portions separate from each other and each formed partly in one section and partly in the other, there being a portion wholly in one of the sections connecting said two parts of the passage, substantially as described.

2. Alstopper for a non-rellable bottle consisting of two pieces together forming a substantially cylindrical body, one of said pieces having within it a recess with a third piece therein, said recessed piece having a passage partly formed in it and partly in the third piece and there being other passages extending partly in the first piece and partly in the second, from the ends of the first passage to the ends of the stopper, substantially as described.

3. A stopper for a non-rellable bottle consisting of three pieces, two of said pieces forming together a cylindrical body and one of the same being recessed for the reception of the third piece, a three-part passage extending through the stopper, the beginning and end of said passage being formed partly in each of the main pieces of the stopper and the middle portion of said passage being formed partly in one of said main pieces and partly in the piece contained within the recess of said piece, substantially as described.

4. A stopper for a non-reiillable bottle having within it three passages forming a continu- .ous channel-opening on each end of the stopper, two of said passages being united by the third passage, said third passage and one of the other passages each having a valve-seat and a valve, substantially as described.

A stopper for a non-refillable bottle consisting of three pieces, two of said pieces forming together a cylindrical body and one of the same being recessed for the reception of the third piece, a three-part passage extending through the stopper, the beginning and end of said passage being formed partly in each of the main pieces of the stopper and the middle portion of said passage being formed partly in one of said main pieces and partly in the piece contained within the recess of said piece, with a valve at the inner portion of the passage and a second valve in the central portion of the passage, substantially as described.

6. A stopper for a non-reillable bottle, the same consisting of two parts forming together a cylindrical body, and a third part held within a recess in one of the other parts of the stopper, a passage having three portions of which the first and last are formed partly in each of the two parts of the stopper forming the cylindrical body and the third is IOO IIO
